Abstract

Un détecteur de position sans contact, présentant un détecteur primaire et un détecteur secondaire, détecte les déplacements relatifs entre deux objets. Le détecteur secondaire peut fonctionner comme élément de détection de fin de course dans un circuit interrupteur de fin de course, et est positionné pour se trouver dans le parcours du flux magnétique non détecté par le détecteur primaire. Le détecteur primaire est positionné dans un parcours de flux entre des sections d'un pôle de convergence de flux. Un détecteur secondaire est positionné dans un parcours de flux de fuite, extérieurement au premier détecteur, ou peut être positionné dans un parcours de flux secondaire.
